Here’s a screen shot from a post on another forum, it’s a decent guide.
My Tikka 1-10” shoots 50 gr bullets very well but doesn’t like the 75 grainers.
My Tikka Varmint 1-8” shoots 75 gr ELDM like a house on fire.

That works for me. I have a Remington 700 with a 1 in 9 twist that prefers the 40 to 60 grain bullets. My 1 in 8 twist with a 223 Wylde chamber prefers the 69 to 75 grain bullets.
